3-channel FWDM (Filtered WDM) module in LGX cassette form factor — the standard passive for combining or separating 1310 nm upstream PON, 1490 nm downstream PON, and 1550 nm CATV / RFoG video overlay signals on a single fiber. Drops into any LGX-compatible patch panel chassis or ODF cassette slot.
Typical insertion loss is < 0.6 dB on the 1310 nm pass channel, < 0.6 dB on the 1490 nm channel, and < 1.0 dB on the 1550 nm channel. Channel isolation > 40 dB adjacent and > 50 dB non-adjacent; return loss > 50 dB; PDL < 0.3 dB; operating temperature -40 to +85 °C.
Front-face connectors are user-specified — LC/UPC, LC/APC, SC/UPC, SC/APC, and FC/PC are stock; custom wavelength combinations (e.g., 1270 / 1330 / 1550, or 1490 / 1577 for NG-PON2) are available on request. Each cassette ships with a per-channel IL / isolation / RL test report and an SOP for FTTH triplexer installation.
